What is the perimeter of a rectangle with a length of 8 cm and a width of 3 cm?

Explanation:
To find the perimeter of a rectangle, you can use the formula: Perimeter = 2 × (length + width) In this case, the length of the rectangle is 8 cm and the width is 3 cm. First, calculate the sum of the length and width: Length + Width = 8 cm + 3 cm = 11 cm Next, multiply that sum by 2 to find the perimeter: Perimeter = 2 × 11 cm = 22 cm Thus, the perimeter of the rectangle is 22 cm, confirming that the calculated value matches the correct choice. This process emphasizes how adding the dimensions together and then multiplying ensures that you accurately find the total distance around the rectangle.
